Make Every Electrical Estimate Clear. Keep Every Job Organized.
From troubleshooting to materials, labor units and approved installations, connect the details an electrical contractor needs before and after the quote.
Start with the right Electrical tool
Choose a free starting point, the complete one-time toolkit, or separately billed cloud software.
The $99 toolkit is a standalone digital download; cloud workspace access is a separate recurring subscription.
Built around real electrical jobs—not generic paperwork
NECA's labor-unit approach recognizes that installation conditions influence productive time. A material quantity by itself is not a credible total installed-cost estimate.
The core SGL buying path is the complete one-time Electrical business toolkit. If you only need one piece of the workflow, the calculator, forms, proposal builder and operating tools can also be explored individually.
A realistic electrical job example
A homeowner requests four new receptacles and a lighting replacement. Distinguish replacement at existing locations from new branch-circuit or wiring work. Count devices and fixtures, record circuit and panel access, estimate labor by task, and itemize materials, access work and coordination. Any concealed condition requiring added work becomes a separate customer-authorized change.

From defined electrical scope to an organized business record
Compare task quantities, material allowances, time and approved changes. The complete industry listing shows the available components and file formats.
The business workflow, step by step
Step 1
Define the electrical scope
Specify diagnostic versus installation work, locations, devices, circuits and known site conditions.
Step 2
Estimate labor and material
Build quantities for devices, boxes, conductors and related materials; assess installation conditions and crew time.
Step 3
Document authorization
Use clear proposal scope and an approval trail for changed quantities or newly discovered work.
Step 4
Close and review
Keep completion notes, invoice details and actual labor against the estimate for future bids.
Start with the whole toolkit—or choose only what you need
For an owner managing repeated jobs, the complete toolkit is the primary way to explore the industry edition. Every component also has its own product listing so you can compare the scope before deciding.

Electrical business systems: common questions
How do electrical contractors estimate labor?
Break the work into defined tasks, estimate quantities and labor units or hours, then adjust for site conditions, travel, supervision and business overhead.
What is included in an electrical quote?
Known devices and circuits, materials, labor, access assumptions, scope boundaries, work authorization, timing and price.
Should troubleshooting be included with installation?
Only when the diagnostic work and installation scope are agreed together. Otherwise, keep the diagnosis and approved work separately identified.
